Description
The PMJOOO is a 4- or 6-place (depending on model), panel-mounted inter-
com with multiple volume and VOX (voice activated squelch) circuits us-
ing unified volume and squelch controls for the pilot, copilot and passen-
gers.
With few controls for the pilot to use, the operation of the PM3000 is v~ry_ . ..,_ ·
straightforward. Yet the unit outperforms its much more complicated com-
petition. Although there is only one volume control knob, when an adjust-
ment is made to the volume control, all output amplifiers are being changed
simultaneously. Likewise, when the squelch control knob is adjusted, sev-
eral VOX circuits are being changed at the same time. Since the system is
designed to use modem stereo headsets, it is not necessary to balance the
volume and squelch controls at the intercom.
The PM3000 has an automatic fail-safe interconnect to the aircraft radios.
If
power is disrupted to the intercom for any reason, an internal relay will
connect the pilot's headset to the aircraft radio allowing continued radio
communicati,ons.
Provision for entertainment input allows the pilot, copilot and passengers
the option to listen to music during flight. During intercom or aircraft radio
reception, this music will automatically mute to allow communications

without distraction. When the activity ceases, ·the Soft Mute™ circuit
gradually returns the music to the original listening volume. By depressing
the "Mute" control (located on the Squelch knob) once, it is possible to
have the music remain at a constant level, regardless of any ICS or radio
traffic.
During various phases of flight, the degree of importance of the aircraft
radio will vary. Because the "ISO" mode connects the pilot directly to the
aircraft radio, select the "ISO" mode when the pilot must have top priority
on radio transmissions.
Both pilot and copilot have transmit capabilities over the radio. The
PM3000 only allows the voice of the person who presses their PTT to be
transmitted over the aircraft radio.
If
both pilot and copilot press the PTT at
the same time, the copilot will override. When either pilot or co-pilot
presses PTT, all other microphones are disabled. The pilot can regain prior-
ity by switching the unit off.
Approval Basis
The
PMJOOO,
part number 11931 or 11932 is FAA-approved under TSO-
C50c, and RTCA, Inc. D0-214. Due to the fact that there is no TSO for the
recorder function in the 11933 and 11934, these units are not fully TSO-
approved. It is the responsibility of the installer to determine the approval
basis for these units.
